I wanted to re-install Ubuntu (dual boot with Win10) to have it on a larger partition (ran out of space beforehand). To do this, I have changed the boot order to have it boot directly to Win10, and then I deleted and merged the partition with the Win10 partition. I have also deleted the ubuntu boot folder via Diskpart (as explained here).
Then, I created a new (larger, 100GB) partition and created a live USB with the latest 20.04 release from the Ubuntu website, but when I boot from this USB I do not get the 'install ubuntu' option. The only options are (similar to this):
- Ubuntu
- Ubuntu (safe graphics)
- OEM install (for manufacturers)
- Boot from next volume
- UEFI firmware settings
So, the things I have tried didn't work, and I was curious if anyone here has another suggestion as to what may help me install my dual boot. Things I tried:
- Disabled secure boot
- Disabled fast startup
- Tried creating live USB with Rufus and Universal USB Installer
- Tried all options, the first three give me a black screen and the fourth boots to Win10, fifth goes to UEFI
- Tried to manually boot into the three available EFI files on the live USB (BOOTx64.efi, grubx64.efi, mmx64.efi)
- Looked for booting in legacy mode (as suggested here) but my UEFI doesn't show this option
Additionally, in the UEFI the only option it gives next to the Windows Bootloader is booting from the USB itself, which usually should get me to the 'install Ubuntu' option.
I have no idea what to try next, but my friend suggested that somehow the USB may think that a version of Ubuntu is still installed (maybe some remnants from the deleted install?), and will therefore try to boot it but can't find it, hence the black screen. Please let me know if you have any suggestions!
